This can be due to the phone re-optimizing itself after the update or apps needing to be optimized for the new firmware.
Add apps to the "deep sleep" list to prevent them from running in the background and draining battery.

Clear app cache to remove temporary data that can impact performance and battery usage.
Resetting battery statistics can sometimes help.

Adjust background usage limits in Settings > Battery and device care > Battery > Background usage limits.

Choose options like "Put unused apps to sleep" or "Sleeping apps" to restrict background activity.

Sir I try every possible guidance like factory reset, clear cache and also your Samsung settings but there is no improvement in battery drain. In the night when phone is idle, mobile data is off, location is off and dark mode applied, also I am using 4G network,then my battery in the morning down by 10 points like from 90 to 80, it is a optimisation problem with UI7
